Mounting the Camera
Note
Read before starting work.
• Special skills are required to install this unit.
• Install this unit on a location that is strong enough to hold it.
• Use the appropriate attachment screws and tighten them securely.
• Make sure you turn off the power supply to the device before starting work.
• When you attach the camera body to the ceiling, be sure to wear
safety goggles to protect your eyes from falling objects.
Opening a hole (approx. Φ 30 mm) on
the ceiling or wall
Open a hole (approx. Φ 30 mm) in the ceiling or wall,
and pull the cables out of the hole.
Attach the fall prevention wire
To attach the fall prevention wire, remove the attachment
screws of the fall prevention wire on the bottom of the camera
body (the fall prevention wire and cables are not provided).
Note
• Attach the fall prevention wire to a sufficient strong location such as
the ceiling or wall.
• Mount the fall prevention wire using an attachment screw.
•
Take note of the length and strength of the fall prevention wire. Use wire
made of insulated material. Make the wire length as short as possible.
• Use the appropriate attachment screws and tighten them securely.
• Use stainless steel attachment screws. If you use stainless steel
screws, apply rust-proofing, for example, by painting them after
installation. Tighten the screws securely so that the unit will not fall off.

Waterproofing
Filling the dust hole and the mounting holes (two
locations) with waterproof seal material (GE silicon).
Waterproof treatment (three locations)

for convenience of explanation.
After adjusting images, place the silica gel in the location
shown in the diagram below.

* Fix the silica gel
so that it will not
fall off.

Insertion space
Note
• Take silica gel out of the aluminum pack, place in the space for
inserting silica gel inside the camera body, and fix it using the rug
plate.
• Completely plug the duct hole and the mounting holes. Water and
moisture may get inside and fog the lens and dome cover.
• If it is raining when you install the unit, exercise care to prevent any
rain from entering.
• Be sure to place silica gel. If you use a type of silica gel other than
that supplied with this unit, the camera lens and the dome cover may
become fogged.
• When you open the dome cover for repair or maintenance, replace
the silica gel.
• Correctly waterproof all the cables using waterproof tape (adhesive).
• If you do not adjust the field angle (
☞ Page 3) immediately after
installing the camera, place the silica gel when adjustment is
finished. The effects of silica gel wear off if it is exposed to air for a
long period of time.
• Apply seal materials to or caulk the gap between the camera and the
ceiling or wall.
Secure the camera to the ceiling or wall
After connecting the cables, attach the camera to the ceiling (or
on the wall).
Use the attachment screw (approx. Φ 4 mm) to secure the
camera body to the ceiling or wall.
When you mount it, align the shooting direction mark with the
range you want to shoot.
Note
•
Check to ensure that there is no gap between the ceiling and the camera.
• Ensure that neither the cables nor the fall prevention wire of the
dome cover are tucked in.

Using the duct hole on the side
Loosen the fastening screws (M3 x 6 mm) and remove the
plug for the duct hole using a flat-blade screwdriver.
Note
• When you insert a pipe, do not insert it deeper than 12 mm. Inserting
it further may damage the inside of this unit.
• If you install the unit, using the duct hole on the bottom or on the side,
wrap seal tapes around the connecting parts (the point where the thread
of the duct hole and the screw hole meet) of the duct at least twice.

(VN-H257VPU)
Connect the AC 24 V power cable, alarm cable, and audio cable to
their respective connectors by crimping them or soldering them.
Wrap unused connectors and the ends of unused cables with insulation
tape and waterproof tape.
Make sure the LAN cable is completely inserted into the connector.
After confirming the connection, waterproof it by wrapping it with
waterproof tape.
Attach the supplied ferrite core only to the Alarm I/O cable. (VN-H257VPU)
Securely attach the fall prevention wire to a section that is sufficiently
strong (a slab or channel).
Note
• Always use the AC 24 V power supply that is insulated from the
primary power circuit. An autotransformer or similar single winding
transformer may fail or damage the camera.
• If you use both the AC 24 V power cable and the PoE-based LAN
cable simultaneously, the camera may fail. Always supply power
using either method.
Memo
• Put the cables into the hole that you opened on the ceiling or wall
after connecting.
Connecting the LAN cable
When using the duct hole at the bottom of the base or on
the side, attach the LAN cable as follows.
